Dor orofacial e qualidade de vida de adultos

To determine the prevalence and intensity of orofacial pain in adults that participated in a health program at Ribeirão Preto. Methodology: The study was conducted by a self-administered questionnaire, with 19 questions in 99 people aged 18 to 66 years. The method used for data collection was the index Oral Impacton Daily Performances (OIDP), which evaluated the six months preceding the survey, pain experiences in the mouth, teeth or dentures and how these factors interfere with daily activities. Statistical analysis was performed using Epi Info version 3.4. Results: The majority of the adults who participated in this survey (52.5%) reported having an excellent or good oral health, reported having problems with their teeth (60.6%), no problems with the gums (77.8%), no bad taste in mouth (77.8%) or bad breath (77.8%). Among the participants of the study, 56.6% felt orofacial pain in the last six months and the pain were more frequently caused by cold or hot liquids (30.3%), spontaneous pain (17.2%), during the mouth opening (17.2%), pain in the face (13.1%) and ATM (13.1%). Regarding the severity rate, the highest proportion varied from mild to moderate. Conclusions: Even observing a low severity of orofacial pain, its prevalence was high, which probably has a negative effect on life quality of these people.

Avaliação sensorial e influência do tratamento térmico no teor de ácido ascórbico de sorvete de pimenta

In this work were prepared with three ice cream added peppers of different varieties: Capsicum baccatum, Capsicum annuum and Capsicum frutescens. The peppers were first pasteurized and evaluated in relation to the effect of heat treatment on the ascorbic acid content. Results showed that the Capsicum annuum showed higher ascorbic acid content, but the heat treatment resulted in greater loss of biocompounds. The higher retention of ascorbic acid was observed with Capsicum frutescens, which presented lower content of biocompound, but near of the pepper Capsicum annuum. The follow attributes was performed to evaluate the acceptance of ice cream through the sensory attributes: color, aroma, flavor and texture. Analysis of variance showed no significant difference between ice cream formulations at the 5% level of significance with regard to color, aroma and texture. Regarding taste, the samples differed significantly, at 5% significance, and the most preferred was the ice cream made with pepper Capsicum frutescens.

Desenvolvimento e avaliação físico-química, sensorial e da estabilidade de ácido ascórbico de doce de leite com pimenta

The dulce de leche or milk candy is a food widely consumed in Brazil, which shows typical characteristics of taste, color, flavor and texture. The lady-finger red pepper is regularly present on the Brazilian people table as this product contains a pungent flavor favoring various spices; and it is also rich in ascorbic acid (vitamin C) which is an excellent antioxidant. This study aimed at developing a dulce de leche containing lady-finger red pepper, and to determine the composition of the product. Also, the ascorbic acid contents were quantified in products stored for different periods (0, 30 and 60 days). The product acceptance by consumers on the sensory characteristics was evaluated by means of hedonic scale for color, aroma, flavor and texture attributes. The composition of the product was in accordance with the legislation in force, and the ascorbic acid contents were practically stable during the storage, and the sensory analyses indicated that the red pepper-containing dulce de leche was well accepted.

Effect of essential oil from Citrus aurantium in maternal reproductive outcome and fetal anomaly frequency in rats

Citrus aurantium L., commonly known as bitter orange, is widely used in folk medicine, but there is little data in the literature about the s on pregnancy. The aim of the present study was to evaluate the influence of essential oil obtained from fruits of Citrus aurantium on the maternal reproductive outcome and fetal anomaly incidence in rats. Pregnant Wistar rats were randomized into four groups (n minimum = 12 animals/group): G1 = control, G2 to G4 = treated with essential oil from C. aurantium at dose 125, 250 and 500 mg/kg, respectively. Rats were orally treated, by gavage, with plant essential oil or vehicle during pre-implantation and organogenic period (gestational day 0-14). On gestational day 20 the rats were anaesthetized and the gravid uterus was weighed with its contents and the fetuses were analyzed. Results showed that the treated group with 500 mg/kg presented decreased placental weights and placental index, although the treatment with bitter orange essential oil did not show any alteration in maternal reproductive performance, toxicological , changes in ossification sites, and malformation index. In conclusion, the treatment of Citrus aurantium essential oil was not teratogenic and did not alter the maternal reproductive outcome.

Tratamentos pré-germinativos e substratos na emergência de sementes e qualidade de mudas de pinhão manso (Jatropha curcas L.)

The physic nut can be propagated asexually or sexually. Using cuttings have been earlier yield and more fidelity characteristics of the parent plant. However, there is less initial vegetative growth. The seeds from the plants have increased genetic variability, are more vigorous and begin production later. To get quality changes, the substrate is an important factor. With that the objective was to taste pre-germinated treatments and different substrate on seeds emergence and quality physic nut seedlings. The experimental design was completely randomized, in factorial scheme 6 x 3 (pre-germinated treatments x substrate), 18 treatments and 4 repetition, 8 seeds to each repetition. It was evaluated six pre-germination treatments: T1: witness (without treatments); T2: water immersion for 12 hours; T3: water immersion for 24 hours; T4: mechanical scarification; T5: mechanical scarification + water immersion for 12 hours; T6: mechanical scarification + water immersion for 24 hours, using as substrate: commercial, expanded vermiculite and sand washed. The mechanical scarification was realized opposite the micropyle using sandpaper n. 60. After the pre-germination treatments, the seeds were emergence in plastic cups (200mL) with substrates. We evaluated the characteristics: percentage, beginning and emergence speed index, mean length of plant, diameter of plant stem, SPAD index, fresh and dry shoot and root. The results showed that in seeds of Jatropha do not need pre-germinative treatments; and the use of commercial substrate showed seedling development.

Photocatalytic and photoelectrochemical inactivation of Escherichia coli and Staphylococcus aureus

Water disinfection usually requires expensive chemicals or equipment. Chlorination is a common disinfection method, although it is not able to inactivate all pathogens. High concentrations of residual chlorine also cause an unpleasant taste and smell in drinking water. As an alternative, photocatalysis and photoelectrochemical treatment has a high disinfection potential in drinking water by using solid catalysts, such as titanium dioxide. Highly reactive hydroxyl radical generated during the process serves as the main oxidant, capable of inactivating a wide range of microorganisms. In this study, we proposed a novel comparison between Gram-positive and gram-negative microorganisms. An immobilized TiO2 film promoted higher efficiency in water disinfection processes. The treatment effectively inactivated Escherichia coli and Staphylococcus aureus bacterial microorganisms in a shorter period than other alternative methods.

Three-dimensional aspects of the lingual papillae and their connective tissue cores in the tongue of rats: a scanning electron microscope study

The aim of the present study was to describe the tridimensional morphological characteristics of the lingual papillae and their connective tissue cores (CTCs) in Sprague Dawley rats. Four types of papillae were reported on the dorsal surface. Filiform papillae were distributed on the tongue surface and after epithelial maceration a conic and multifilamentary shape of the CTCs was revealed. Fungiform papillae were reported on the rostral and middle regions covered by a squamous epithelium. After the removal of the epithelium, the shape of a volcano with the taste orifice at its top was noted. Foliate papillae were composed of five pairs of epithelial folds situated on the lateral-caudal margin of the tongue. After the removal of the epithelium, they were shown to be limited by thin laminar projections. The vallate papilla with an oval shape was present in the caudal region and delimited by an incomplete groove. The morphological characteristics of the lingual papillae of Sprague Dowley rats, three-dimensional SEM images, and the types of papillae on the dorsal surface were similar to those reported previously in other rodent mammals. The maceration technique revealed the details of extracellular matrix with varied shapes form of connective tissue cores.

Objective: Evaluate the impact of the use of strip adhesive over the quality of life of institutionalized patients and wearers of complete dentures. Material and method: Twenty-nine institutionalized patients wearers of complete denture were selected to this study and after a clinical exam, a questionnaire (adjusted and based upon the index of Oral Health Impact Profile and Oral Health-Related Quality of Life, OHIP and OHQOL) was applied to evaluate issues related to epidemiological conditions (gender and age), quality of life (pain, discomfort, functional limitations, phonetic, social, psychological and esthetic), taste and notion of implant treatment. Following this part, the patients received instruction to use the strips adhesives (Corega Fita Adesiva, Glaxo-Smith-Kline, Rio de Janeiro, Brazil), considering three in maxillary prosthesis and two in the lower prosthesis during a period of 30 days. After this period, all the patients were recall and the questionnaire was reapplied; add some adhesive performance questions, to compare the results before and after the adhesive use in terms of percentage. Result: After the adhesive strips use there were improvement of the functional, social and physcological limitation aspects, but without percentual increasement of phonetic and esthetics aspects. The results showed 65.5% of the answers stating adhesive maintenance between 6-12 hours, easy removal (68.9%), and without change the taste (89.6%). The notion for implant treatment was decreased changing from 75.8 to 37.9% after the adhesive use. Conclusion: The results enhanced a positive impact over quality of life of the respondents after the strip adhesive use, showing decrease of pain and discomfort, mainly of inferior dental prosthesis.

Ectopic third molar as a cause of sinusitis

Ectopic third molar teeth are those that are impacted in unusual positions, or that have been displaced and are at a distance from their normal anatomic location. Ectopic eruption of a tooth within the oral cavity is common, but rare in other sites. Ectopic eruption can be associated with developmental disturbances, pathologic processes or iatrogenic activity. Male, 19- years old, with an upper left ectopic third molar located in the maxillary sinus-infraorbital region. The patient reported a bad taste and recurrent sinusitis that had been resistant to treatment. Surgical excision was carried out of the third molar tooth using the Caldwell-Luc approach.

Qualidade de vida de pacientes submetidos à radioterapia para tratamento de lesões malignas de cabeça e pescoço

In order to evaluate the quality of life of patients with head and neck cancer, this study analyzed data of 24 patients with squamous cell carcinoma, which indicated therapy was radiotherapy or not be combined with chemotherapy and surgery. The study was conducted in the Unit of Radiotherapy of Megavoltage located in the São José de Rio Preto-SP, in the period August 2007 to January 2008. Then, it was used the questionnaire of quality of life from University of Washington which enabled the identification of different quality of life patterns associated with the different stages of radiotherapy, indicating to be viable the prospect of recognition of prognostic factors of reduction in multiple domains of quality of life. From the data collected and analyzed, it was identified that the areas with the worst score in the begin of radiotherapy were appearance, speech and anxiety; during the treatment were taste, saliva and anxiety; and in the end were taste, saliva and swallowing. Throughout the treatment, it was observed the deterioration of patients' mood. In this regard, emphasizes the importance of dental and psychological follow-up, within the framework of a multidisciplinary care for patients with head and neck cancer during radiotherapy treatment.

Role of alfa2-adrenoceptors in the lateral parabrachial nucleus in the control of body fluid homeostasis

Central α2-adrenoceptors and the pontine lateral parabrachial nucleus (LPBN) are involved in the control of sodium and water intake. Bilateral injections of moxonidine (α2-adrenergic/imidazoline receptor agonist) or noradrenaline into the LPBN strongly increases 0.3 M NaCl intake induced by a combined treatment of furosemide plus captopril. Injection of moxonidine into the LPBN also increases hypertonic NaCl and water intake and reduces oxytocin secretion, urinary sodium, and water excreted by cell-dehydrated rats, causing a positive sodium and water balance, which suggests that moxonidine injected into the LPBN deactivates mechanisms that restrain body fluid volume expansion. Pretreatment with specific α2-adrenoceptor antagonists injected into the LPBN abolishes the behavioral and renal effects of moxonidine or noradrenaline injected into the same area, suggesting that these effects depend on activation of LPBN α2-adrenoceptors. In fluid-depleted rats, the palatability of sodium is reduced by ingestion of hypertonic NaCl, limiting intake. However, in rats treated with moxonidine injected into the LPBN, the NaCl palatability remains high, even after ingestion of significant amounts of 0.3 M NaCl. The changes in behavioral and renal responses produced by activation of α2-adrenoceptors in the LPBN are probably a consequence of reduction of oxytocin secretion and blockade of inhibitory signals that affect sodium palatability. In this review, a model is proposed to show how activation of α2-adrenoceptors in the LPBN may affect palatability and, consequently, ingestion of sodium as well as renal sodium excretion.
